I'm not sure if you mean
1.%284%2F5%29%2F%28n%2B13%29
or if you mean
2.%284%2F5%29%2F%28n%29%2B13
Either way, here goes.
Substitute for n=1/5,
1.%284%2F5%29%2F%28n%2B13%29=%284%2F5%29%2F%28%281%2F5%29%2B13%29
You need a common denominator to add fractions.
1.%284%2F5%29%2F%28n%2B13%29=%284%2F5%29%2F%28%281%2F5%29%2B%2865%2F5%29%29
1.%284%2F5%29%2F%28n%2B13%29=%284%2F5%29%2F%2866%2F5%29
Dividing by a fraction is equivalent to multiplying by the reciprocal.
1.%284%2F5%29%2F%28n%2B13%29=%284%2F5%29%2F%2866%2F5%29=%284%2F5%29%285%2F66%29
1.%284%2F5%29%2F%28n%2B13%29=%284%2F5%29%2F%2866%2F5%29=2%2F33
.
.
.
And now for 2.
2.%284%2F5%29%2F%28n%29%2B13=%284%2F5%29%2F%28n%29%2B13
2.%284%2F5%29%2F%28n%29%2B13=%284%2F5%29%2F%281%2F5%29%2B13
2.%284%2F5%29%2F%28n%29%2B13=%284%2F5%29%2A%285%2F1%29%2B13
2.%284%2F5%29%2F%28n%29%2B13=4%2B13
2.%284%2F5%29%2F%28n%29%2B13=17
